HVAC-Ptech vs. split ductless vs. zoned - which do you recommend?

[Marvin Meng]

Hi, I'm in the middle of rehabbing a 4-BR SFR and just discovered that the old AC (which will probably need to be replaced anyway) is not ducted to the upstairs (two) bedrooms. Adding zoned HVAC seems a little exorbitant so I'm debating between a Ptech in each bedroom (hotel-style wall mounted) or a split coil ductless system. Does anybody have any feedback with either and any recommendations?

Than you!
